Where foreign exchange was brought into India by the tenderer against declaration on Currency Declaration Form (CDF), he should be asked to produce the form. The production of CDF need not be insisted upon if the tenderer is unable, for any reason, to produce it. Where CDF is produced, particulars of purchases made should be endorsed on the reverse of the form giving number and date of the encashment certificate issued to the tenderer under the stamp and signature of authorised dealer/exchange bureau. If the entire foreign exchange covered by the CDF is encashed, CDF should not be returned to the tenderer, but retained by the authorised dealer or exchange bureau. The exchange bureaux should submit the fully used CDFs to Reserve Bank along with the monthly statement of purchases and sales of foreign currency notes/coins.
NOTE: In cases where foreign exchange offered for sale by traveller had been originally obtained from an authorised dealer/exchange bureau/authorised money-changer in India, the repurchase thereof should on request be endorsed on the travellers passport in red ink.
